The difference between solar cables and PVC Cables

October 24, 2019

  The characteristics of solar cables are determined by the special insulation material and sheath material of the cable. We call it cross-linked PE. After the irradiation of the irradiation accelerator, the molecular structure of the cable material will change, thus providing its performance. .

 

  Solar cables are often exposed to sunlight, and solar systems are often used in harsh environmental conditions such as high temperatures and ultraviolet radiation. In Europe, sunny days will cause the solar system to have an on-site temperature of up to 100 °C. At present, we can use various materials such as PVC, rubber, TPE and high quality cross-linking materials, but unfortunately, rubber cables with a temperature of 90 ° C, and even PVC cables with a temperature of 70 ° C. It is also often used outdoors. At present, the national Golden Sun Project is frequently launched. Many contractors do not choose solar system special cables in order to save costs. Instead, they choose ordinary pvc cables instead of photovoltaic cables. Obviously, this will greatly affect the life of the system.

  In fact, during installation and maintenance, the cable can be routed over the sharp edges of the roof structure while the cable is subjected to pressure, bending, tension, cross-tension loads and strong impact. If the cable jacket is not strong enough, the cable insulation will be severely damaged, affecting the life of the entire cable or causing problems such as short circuits, fire and personal injury.
